How to get random rows from SQL Server Table - TSQL Tutorial Part 117
 
09:50
SQL Server / T-SQL Tutorial Scenario: How to get random rows from SQL Server Table Scenario: You are working as SQL Server developer. You are asked to provide sample random data from dbo.Customer table. You might asked to provide random 100 rows or some percent of total data from table. What query you will use to provide required output? Solution: In previous post, we learnt how to get top n rows from table. We can either provide row count or percent of records we want to get from a table by using TOP in our select query. We can use the same Top clause but as we are asked to provide the random records, we need to sort them randomly first. We can use newid() function in order by clause to sort them randomly.

For example, the following "UPDATE" query, updates a set of rows that matches the condition in the "WHERE" clause at the same time. Update tblProductSales Set UnitPrice = 50 where ProductId = 101 However, if there is ever a need to process the rows, on a row-by-row basis, then cursors are your choice. Cursors are very bad for performance, and should be avoided always. Most of the time, cursors can be very easily replaced using joins. There are different types of cursors in sql server as listed below. We will talk about the differences between these cursor types in a later video session. 1. Forward-Only 2. Static 3. Keyset 4. Dynamic Let us now look at a simple example of using sql server cursor to process one row at time. We will be using tblProducts and tblProductSales tables, for this example. On my machine, there are 400,000 records in tblProducts and 600,000 records in tblProductSales tables. If you want to learn about generating huge amounts of random test data, please watch Part - 61 in sql server video tutorial. The link is below. http://www.youtube.com/user/kudvenkat/videos?flow=grid&view=1 Cursor Example: Let us say, I want to update the UNITPRICE column in tblProductSales table, based on the following criteria 1. If the ProductName = 'Product - 55', Set Unit Price to 55 2. If the ProductName = 'Product - 65', Set Unit Price to 65 3. If the ProductName is like 'Product - 100%', Set Unit Price to 1000 For the SQL code samples used in the demo please visit my blog at the following link http://csharp-video-tutorials.blogspot.com/2013/01/cursors-in-sql-server-part-63.html The cursor will loop thru each row in tblProductSales table. As there are 600,000 rows, to be processed on a row-by-row basis, it takes around 40 to 45 seconds on my machine. We can achieve this very easily using a join, and this will significantly increase the performance. We will discuss about this in our next video session. To check if the rows have been correctly updated, please use the following query. Select Name, UnitPrice from tblProducts join tblProductSales on tblProducts.Id = tblProductSales.ProductId where (Name='Product - 55' or Name='Product - 65' or Name like 'Product - 100%')

OFFSET FETCH NEXT in SQL Server
 
06:49
Click here to Subscribe to IT PORT Channel : https://www.youtube.com/channel/UCMjmoppveJ3mwspLKXYbVlg This Feature Enabled from SQL Server 2012. OFFSET FETCH clause provides you with an option to fetch only a window or page of results from the result set. OFFSET-FETCH can be used only with the ORDER BY clause OFFSET - Specifies the number of rows to skip, before starting to return rows from the query expression. The argument for the OFFSET clause can be an integer or expression that is greater than or equal to zero. You can use ROW and ROWS interchangeably. FETCH - Specifies the number of rows to return, after processing the OFFSET clause. The argument for the FETCH clause can be an integer or expression that is greater than or equal to one. You can use ROW and ROWS interchangeably. Similarly, FIRST and NEXT can be used interchangeably Limitations in using OFFSET FETCH ORDER BY is mandatory to use OFFSET and FETCH clause. OFFSET clause is mandatory with FETCH. You can never use, ORDER BY … FETCH. TOP cannot be combined with OFFSET and FETCH in the same query expression. The OFFSET/FETCH rowcount expression can be any arithmetic, constant, or parameter expression that will return an integer value. The rowcount expression does not support scalar sub-queries.
